Abstract

Aparato para producir los tonos de una escala musical, cuyo aparato comprende un convertidor de frecuencia, una salida del cual está conectada a la entrada de una cadena de divisores a la cual se puede aplicar la señal precedente de un oscilador, estando conectadas las salidas de divisores dados a entradas de un circuito de puerta cuya salida está conectada a una salida del convertidor de frecuencia, en cuya salida se obtiene un tono inferior de la octava, caracterizado porque para cada tono de la octava existe un convertidor de frecuencia de la citada clase, estando las salidas de los divisores del mismo conectadas a entradas del circuito de puerta que producen la salida de este circuito de puerta un tono que tiene una frecuencia siguiente inferior a la frecuencia del tono en la entrada de la cadena de divisores, estando conectados en serie todos los convertidores de frecuencia.
